Key takeaways

  • Short sellers are aggressively piling into QSRs (quick service restaurants). Domino's is now the third most shorted stock on the market, having experienced a sharp 2.5% week-on-week increase in short interest. As Macquarie noted earlier this month: "The key pivot on strategy is DMP seeking to transition from a promotional-heavy (i.e., coupons/discounts) pricing strategy to more of an 'everyday low price' offering, which will occur alongside a broader simplification of the menu offering." The analysts see an opportunity for Domino's in menu simplification and cost reduction, though execution risks remain elevated given the company's debt levels.

  • Guzman Y Gomez briefly rallied as much as 26% after its Q1 trading update on 9 October, but suffered a massive intraday selloff, closing down 2.3%. Q1 sales came in below market expectations, with Australasian same store sales growth of 4.0% viewed as relatively soft. While management reaffirmed full-year guidance, several brokers trimmed earnings forecasts due to subdued momentum and slightly higher-than-expected US losses. The $100 million buyback drew mixed reactions, with some viewing it as premature given the company's high valuation.

Key takeaways

A massive week for rising shorts suggests the market is betting against several interesting themes:

  • Gold miners (GMD, EVN, RMS): This might reflect stocks that are overvalued relative to peers, or those with hedges/integrating recently acquired assets.

  • Copper names (SFR, EVN): The sector faces an interesting dynamic as approximately 7% of global supply has been lost in recent months due to downgrades from various major copper mines. While copper stocks have surged, copper prices remain relatively stagnant as demand-side weakness persists.

  • High-multiple stocks (GYG, SEK, HUB, ARB, PME): These names may be targeted as they're all trading at expensive multiples, either relative to peers, their sector, or historical averages.

  • Recent gap-down victims (GEM, ACL, ELD, MYR, IPH, VNT, TWE): All have experienced significant one-day selloffs in recent months, driven by weaker-than-expected earnings (either FY25 results or recent trading updates) or company-specific announcements.

Key takeaways

  • Capstone rallied as much as 77% between August and early October. Despite a ~15% pullback from recent highs, the rally likely squeezed out most bearish bets against the company.

  • Audinate was once a tech stock that was on its way to achieve darling status, having rallied ~150% between August 2023 and March 2024. But the stock collapsed as much as 80% between its March 2024 all-time high and September 2025 low, following a series of earnings downgrades and significant challenges from inventory normalisation and softer demand. The stock has managed to bottom in recent weeks, rallying ~55% between 24 September and 13 October, likely driving some short sellers out of the stock
